Bretty first of all a few [?]ns for you
What rod will you be using
What type of reel will you be using
What's the sea bed like, rough, sandy or kelp.
Your mate, how long has he been sea fishing, if he is an old hand he will keep you right,,
Rigs and baits,
When sea fishing i prefere to use the
PULLY RIG, the basics of this rig, if you are lucky enough to get a big un on, the weight of the fish pulls the lead free of the bottom, helping avoid getting four lead in any snares,its called a pully rig because you have your lead line and hook line connected thru a rolling swivel, you have to have a bait clip on your weight for this to work.
Baits, take a selection, fresh lug worm,ragworm,squid, razor fish and if you can peeler crab, cannot go wrong with that little lot mate.
Casting, dont cast as a freshwater angler, have a go at the overhead cast, that might be the easiest for you, then again your mate should give you a few hints,.
Hope this is a little help to you mate,
BTWdont be scared of making an a**e of yourself, hands up any of us who havent, mines firmly down[:I][:I][:I][:I]
Good luck on your outing, and one more thing Bretty be safe,its a big pond you are fishing im mate
catch me if u can
Andy,
